SPECIFICATION forming part of Letters Patent No. 415,452, dated November 19, 1889. Application filed March 28, 1889. Serial No. 305,077. (No model.)

To all whom it may concern.-

Be it known that we, JOHN ll. FRENIER and LEON LE'BLANC, both of Rutland, in the county of Rutland and State of Vermont, have invented a certain new and useful Improvement in Mechanism for Feeding Sand and Water to Stone-Sawing Machines, of which the following is a specification.

Our improvement relates to apparatuses for supplying mixed sand and water to the saws of stone-sawing machines.

IVe will describe an apparatus in detail, and then point out the novel features in claims.

In the accompanying drawings, Figure 1 is a perspective view of an apparatus embodying our improvement. Fig. 2 is a vertical section of a portion of the same, taken through the axis of the pump. Fi 3 is a horizontal section of a distributing hose or nozzle employed therein. Fig. 4: is a vertical section of the same. Fig. 5 is 'a portion of one of the side plates of the pump, showing the arrangement of certain spiral plates therein. Fig. 6 is a detail View, in vertical section, showing a modification of a certain stufiing-box employed. Fig. 7 is a similar View showing still another modification. Fig. 8 is a section showing a modification of the shaft upon which the stuffing-box is mounted.

Similar letters of reference designate corresponding parts in all the figures.

A designates a pump. This pump is retary and comprises side plates a. Between the side plates (0 is arranged a spirally-extending strip A. This strip where it joins the periphery of the pump at its outer extremity leaves an opening A between its convolutions.

B is a box or tank in which mixed water and sand is contained. As the pump rotates, the mixed water and sand is received in the opening A and passed around through aspiral channel formed by the strip A until it reaches the center of the pump, from which it is ejected through an opening a in one of the trunnions A of the pump. The spiral strip A is secured to the side plates a in manner shown more clearly in Figs. 2 and 5 that is to say, it is provided along its edge with projections rvwhich, when the parts are brought together, will extend through openings a in the side plates,'and afterbeing passed through said openings will be riveted up. The hollow trunnion A is provided with acircumfercntial flange, to which one of the plates a is secured by bolts or otherwise. The other trunnion, or A, beyond the other of the side plates a is screw-threaded and receives a not a", thus clamping the pump upon its trunnion. The trunnions A A rotate in bearings A upon the box or tank B. Upon the trunnion A' is mounted a pulley A", by which rotary motion is imparted to the pump.

The outer extremity of the trunnion A is internally screw-threaded, and has secured to it a nozzle B of a stufiingbox. This nozzle is provided centrally with a passage 1) for the water and sand delivered from the pump, and it will be observed that the passage 1) is contracted toward its outer end, so that the force of discharge from the outer end will be increased.

The exterior of the nozzle B is substantially conical, the taper being either from the inner toward the outer end, as shownin Figs. 2, (3, and S, or from the outer toward the inner end, as shown in Fig. 7. In Fig. 8 the taper of the nozzle is shown as slightly curved near its larger end.

C designates the case or shell of the stutting-box. This case or shell is cylindrical. In the examples shown in Figs. 2 and 6 there is fastened upon its extremity, nearer the pump, an inwardly-extending flange c, which may be taken off to introduce packing between the nozzle and the shell. The enlarged end of the nozzle B is shown as provided with a circumferential rim 0', and between said rim and the outer end of the nozzle is a circumferential rabbet 0 The outer extremity of the case or shell 0 is provided with a circumferential and inwardly extending rim or flange 0 which extends into.the rabbet 0 when the case or shell isin position. The rim or flange c is substantially of the same diameter as the interior of the case or shell. In the space between the nozzle 13 and the outer case or shell O is placed any suitable packing C-such, for instance, as hemp.

To the outer end of the case or shell C is secured the enlarged end of an outlet-elbow D, and between said enlarged end of the outlet-elbow and the case or shell A, as well as a. portion of the nozzle B,is placed a washer c". The outer or contracted end of the nozzle 13 extends into the elbow D.

In Figs. 2 and 6 we have shown means for forcing the case or shell 0 and the packing 0 along upon the nozzle B, so as to take up automatically any we'ar either of the packing or of the nozzle which may occur in use. In Fig. 2 such means comprises a weight E, mounted upona long arm of a bell-crank lever E, fulcrumed upon a projection 6, extending from the bearin g A adjacent thereto. The short arm of the said leverbears against the end of the casing O, the weight operating to force the latter forward upon the nozzle B.

In Fig. 6 we have shown between the inner end of the case or shell 0 and the trunnionbearing compression-springs 6 which operate to produce a similar result. By this means the packing is always kept tight.

against the nozzle B, and by the use of the washer 0* leakage of sand and water into andabout the said nozzle will be prevented.

In Fig. 7 we have shown that the taper of the nozzle may be from its outertoward its inner end and the packing O arranged between the nozzle and the case or shell C. In this case pull-strings may be employed to draw the case or shell rearwardly.

The outlet-elbow D communicates with a pipe 1 through which the mixed water and sand is conveyed to a distributing-nozzle G.

The distributing-nozzle G is approximately triangular in shape, and is provided with two main passages G G A valve g may be moved from side toside, so as to partly or wholly close either one of said passages for the purpose of directing the greater portion or all of the water or sand into the other of said passages. lVith each of the passages G G communicate distributing-pipes g g g g, leading to stone sawing machines, the two former communicating with the passage G and the two latter with the passage G \Ve have shown valves 72 h, adapted to close the inner ends of said outlet-pipes. These valves are packed on both of their sides with rubber or other suitable material, and may be manipulated by handles 7L2, (shown as upon the upper side of the nozzle G.) In the lower portion of the nozzle G is a chamber G and communicating with said chamber are passages 11 '11. Openings j in the sides of the passages G l communicate with the passages 71 i. The valves 71 71/ are so hung that they may be swung to open the supply-pipes g',,&c. They then shut the corresponding openings j orj. \Vhen swung to open the openings j y", they close the supply-pipes. \Vhen the supply-pipes are cut off, their corresponding openings j or j are of course opened, and the sand and water then pass into the chamber G, and thence down through the pipe G5 into the base or tank B. Thus the sand and water are flowing continually either through the supply-pipes or back into the tank.

Upon one side of the box or tank B is a tank I-I. Communication is afforded between the tank H and tank 13 through an openingl in the side of the tank B, adapted to be closed by a valve Z;

H designates a pipe communicating near one end with the elbow D and having its other end extendin g into the tank II. In the pipe 11 is arranged a cock Z \Vhen it is desired to stop the operation of the machine, the valve Z is closed and the cock Z opened. All the contained water and sand in the pipe will then flow back into the tank Hi If at the same time the rotation of the pump be continued, all the water and sand contained therein, as well as that contained in theta'nk B, will be caused to flow in the tank II. This is advantageous, because it provides for removing all Water and sand from the pump, and thus preventing the clogging of the pump due to the settling of the sand. By this means, also, all waste of the sand is avoided.
